Light-guiding foils with high optical quality can today already be realized by means of structured coating of (smooth) foils. However, these foils are not suitable for the lighting and photovoltaic applications because they either lack in reliability and / or are too expensive.
The primary goal of the research project is to develop the technological basis for the production (surface structuring) of high quality, light-guiding foils using a "simple" extrusion process. The foils produced in this way would have clear advantages in terms of reliability and costs, compared to the previously available. Another goal of the project is to evaluate the foils for lighting and photovoltaic application environments to maximize opportunities for long-term commercial exploitation activities.
